It is closely related with its pattern, size.In the titanium dioxide of different-shape, 3-D solid structure has surface area big, light absorbs
It is good with light scattering, the advantages of electric transmission is easy, it is had huge application prospect in area of solar cell.Together
When, the preparation method of titanium dioxide is also varied.The preparation method of the titanium dioxide of report mainly has at present：Solvent-thermal method,
Sol-gel process, anodizing etc., are successfully prepared the titanium dioxide nano material of different-shape.Wherein solvent-thermal method by
It is to prepare the conventional method of titanium dioxide nano material the advantages of with simple to operate, low cost, scale topography is controllable.Mesh
Before, in 3 D stereo titanic oxide material preparation process, it usually needs multi-step reacts, and severe reaction conditions, therefore
Technical difficulty is improve, the reappearance of pattern is bad, and toxic reagent and template can be also used sometimes, causes environmental pollution, nothing
Method realizes that a nontoxic step prepares the purpose of 3 D stereo titanium dioxide.
In recent years, flexible perovskite solar cell is received much concern, and flexible substrates used have also been obtained increasingly
Many concerns.The polyethylene terephthalate commonly used at present（PET）Demand has been can not meet with tinsel flexible substrates,
It is badly in need of finding a kind of cheap, novel flexible base material of abundance.Paper, because its have inexpensively, light weight, flexible foldable,
Abundance, it is degradable the features such as be a kind of flexible substrates of great potential.The present invention prepares paper there is provided an a kind of step first
The method of base 3 D stereo titanium dioxide nano material, during need not add surfactant or template, it is possible to achieve
Simple and efficient, inexpensive, the environmentally friendly purpose for preparing paper substrate 3 D stereo titanium dioxide nano material, also causes paper substrate perovskite
Solar cell is possibly realized, and is to be laid a good foundation based on titanium dioxide flexibility perovskite solar cell device.
The content of the invention
